A process is also provided for filtering electromagnetic interference (EMI) in an implanted leadwire extending from an AIMD into body fluids or tissue, wherein the leadwire is subjected to occasional high-power electromagnetic fields such as those produced by medical diagnostic equipment including magnetic resonance imaging.

  • Publication number: 20100055544
    Abstract: A replaceable and versatile hermetical lead-acid cell comprises a top cover and a casing. The top cover has a cap disposed at its top portion. The top cover and casing are sealed together by resin sealable glue filled therebetween. Plural electrode plates, between which dilute sulfuric acid is filled, are positioned in the casing. In addition, a divider is placed between every two electrode plates. Four electrode terminal posts are further provided at the top portion of the top cover and are adjacent to four corners of the top cover. The invention can replace various kinds of cells in marketplace, meet requirements of difference motorcycle, and improve capacity of the cell.

  • Patent number: 7585589
    Abstract: A pouch-type lithium secondary battery includes a battery unit having a positive plate, a separator, and a negative plate; a plurality of electrode tabs drawn from the positive and negative plates, respectively; a case having a space for receiving the battery unit and upper and lower sealing surfaces which are thermally fused to each other; a short-circuit prevention tape attached along the upper and lower sealing surfaces; and a polymer material coated on at least a portion of each electrode tab corresponding to the upper and lower sealing surfaces. A portion of the insulating tape exposed outside the sealing surface of the case is extended and the extended portion of the insulating tape comes in contact with the end portion of the sealing surface after being folded. Therefore, preventing an electrical short circuit between the electrode tab and the intermediate layer of the metal case is achieved.

  • Patent number: 7537720
    Abstract: The present invention provides a protection circuit module (PCM) insert injection mold, and a battery having the same. The PCM insert injection mold is made by inserting a PCM, including a plate having protection circuit formed thereon and connection terminals and optionally leads, with the protection circuit plate, connection terminals and leads being electrically connected, into an inner space of a mold, and injecting a molten resin into the inner space of the mold such that the leads are partially exposed to the outside where the PCM includes the leads, or such that the connection terminals are partially exposed to the outside where the PCM does not include the leads. Since the PCM is prepared by insert injection molding under the condition that the protection circuit and battery cell are not connected, i.e.
